SENSOR OF TURNS OF THE CRANKED SHAFT
Removal
| PERFORMANCE ORDER |
| 1. Remove a weight wire from the accumulator. |
| 2. Disconnect the electric socket of the sensor of a cranked shaft which is located in a motor compartment behind the accumulator. |
| 3. The sensor of a cranked shaft is established on an interfaced surface between the block of cylinders and a coupling case over a starter. Unscrew a bolt and remove the sensor of a cranked shaft from a coupling case. Remove laying. |
|
Installation
| PERFORMANCE ORDER |
| 1. Installation is made in sequence, return to removal. |
|
THE SENSOR OF TEMPERATURE OF COOLING LIQUID
Removal
| PERFORMANCE ORDER |
| 1. Merge a part of cooling liquid from cooling system. Check that ignition is switched off. |
| 2. The sensor of temperature of cooling liquid is located in the left top part of a head of the block of cylinders. |
| 3. Disconnect the electric socket from the sensor of temperature of cooling liquid. |
| 4. Unscrew the sensor and remove a sealing ring. |
|
Installation
| PERFORMANCE ORDER |
| 1. Installation is made in sequence, return to removal. Add cooling liquid in cooling system. |

ELECTRONIC CONTROL UNIT
Removal
| PERFORMANCE ORDER |
| 1. The electronic ELR control unit is established in a back part of a motor compartment. |
| 2. Remove a weight wire from the accumulator. |
| 3. Disconnect the multicontact electric socket from the control unit. |
| 4. Unscrew screws and remove the electronic control unit from a partition of a motor compartment. |

ELECTROMAGNETIC EXECUTIVE MECHANISM
Removal
Side view of a back part of the fuel pump of a high pressure
|
|
A–electromagnetic executive ELR mechanism;
B–electromagnetic executive ARA mechanism |
| PERFORMANCE ORDER |
| 1. The electromagnetic executive ELR mechanism is screwed by bolts on a back part of the fuel pump of a high pressure. On cars with electronic control by turns of idling of ELR and system of an anti-detonation of ARA the electromagnetic executive ELR mechanism is the top block from two blocks located in a back part of the fuel pump. |
| 2. Remove a weight wire from the accumulator. |
| 3. On models without a turbo-supercharging remove the air filter. |
| 4. Disconnect the electric socket from the electromagnetic executive mechanism. |
| 5. Unscrew two bolts and remove the case of the electromagnetic executive mechanism from a back part of the fuel pump. |
| 6. Remove a sealing ring, laying and an intermediate plate. |
